genDlineageGraph

public String genDlineageGraph(EDbVendor vendor,
                               boolean isIndirect,
                               dataflow dataflow)
                        throws Exception

Exception

genDlineageGraph

public String genDlineageGraph(EDbVendor vendor,
                               boolean isIndirect,
                               dataflow dataflow,
                               boolean includeIsolatedNodes)
                        throws Exception

Graph JSON of dataflow.

Parameters:

includeIsolatedNodes - false, what genDlineageGraph(EDbVendor, boolean, dataflow) uses, keeps only the tables, resultsets and columns that take part in a relationship; true also keeps the isolated ones, such as a table a CREATE TABLE declares that nothing reads, or the resultset of SELECT 1 AS n, and the unlinked columns of every node. No relationship is added either way (Mantis 4812).

Throws:

Exception

genERGraph

public String genERGraph(EDbVendor vendor,
                         dataflow dataflow)
                  throws Exception

Throws:

genDataflowGraph

public String genDataflowGraph(Dataflow model,
                               boolean includeIsolatedNodes)
                        throws Exception

Graph JSON of a SQLFlow JSON model.

Parameters:
